Well you will probably need to install CFW to do that. I dont know any way of changing the Buttons around without it.
Do you have MSN because if you do i will help you further through MSN.
Again I strongly recommend editing your post and rmoving the MAC adress as anyone could come in and do stuff with it. I am not sure exacly what you can do with a MAC adress but i beleive it is not brilliant for the PSP owner.
